DEVICE FOR UNROLLING CLOTH OR OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 702,822, dated J' une17, 1902.

Application neat-mary 28,1902. Serial No.91,598 Nom0de1 i T @ZZ whom tmay concern:

Beit known that I, HAERIs L. RosENTHAL, a citizen of the UnitedStates,and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and ImprovedDevice for Unvrolling Cloth or other Fabrics, of which the following isa full,clear, and exact description.

The purpose of the invention is to provide a device especially designedfor unrolling bolts or rolls of cloth or other fabric or material and toso construct the device that it will be simple, durable, and economic,and to provide the device with a revoluble platform and means forcontrolling the movement of the platform, along with means for receivingand sustaining a roll or bolt of cloth or other material removable fromthe platform, yet capable of readyinterlocking engagement 'with theplatform.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional elevation of the deu vice. Fig. 2 is a plan viewof the device, with the sustaining member for the roll or bolt removed;and Fig. 3 is a perspective View of the bottom portion of the roll orbolt sustaining member.

The base A of the device is in the form of a disk, preferably supportedby suitable legs and provided with a central opening 11, surrounded by adownwardly-extending collar 12. A platform B, also preferably in theform of a disk, turns above the base A upon ballebearings 13, mounted toroll in corre sponding grooves produced in opposing faces of theplatform and base. The platform is provided with a central opening 14:,surrounded by a sleeve of sufficient length to extend through theopening 11 in the base and the collar 12 and to a point below thecollar, as is shown in Fig. 1. turns loosely in the collar 12, and thelower end of the sleeve has an exterior thread which receives a nut 16,whereby the platform is The sleeve 15 held on the ball-bearings and inproper relation to the base, but the platform is free to turn upon thebase. At the upper central portion of the platform a socket is producedconsisting of a collar 17, having recesses 18 vertically produced in itsupper edge, as is shown in Figs. 1 and 2. A brake is also provided forthe platform to regulate the speed at which the platform shall turn.This brake, as is best shown in Fig. 1, consists of a screw 19, passedthrough the base A near its periphery, the screw being provided belowthe base with a Asuitable head 20, and above the base near its upperendwith a 001131121, which prevents the screw from leaving the base. Theupper end of the screw 19 may be made to bear with greater or less forceupon the bottom of the platform B, or may be carried entirely out ofengagement With the platform, so that the platform may be made to standperfectly still or may be permitted to turn rapidly or slowly, as thecharacter of the work may demand.

The sustaining member O of the device, adapted to be passed through thecenter of a bolt of cloth O', comprises an upright section 22,preferably fiat at opposite sides and more or less pointed at the top,which upright section is provided with a reduced lower end portion 23 inthe form of a pin, and Where the reduced portion of the upright section22 of the sustaining member connects with the said upright or mainsection or portion a horizontal plate 24 is secured, upon which thebottom of the bolt of cloth C is adapted to rest, and from the underface of the plate 24, at each side of the pin-section 23 of thebolt-sustaining memberC, studs 25 are projected downward from the plate.These studs when the pin 23 is passed into the sleeve of the platform Benteropposing recesses 18 in the col- Ylai-,17' of the socket, as isshown in Fig. 1, and

in this manner the sustaining member of the device is held from turningon the platform B, yet turns with the platform, and the said sustainingmember O of the device may be quickly removed from the platform to bepassed through a bolt of cloth and is quickly and readily brought intointerlocking engagement with the platform, at the same time carrying thebolt with it.

IOO

I desire it to be understood that the device may be used to unroll allkinds of fabric or other material put up in roll form.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a device for unrolling cloth or other fabrics, abase, a platform having rotary motion on said hase, ball-bearingsinterposed between the base and platform, a brake carried by the baseand engaging with the platform, and a sustaining,r member for the boltor roll of cloth, comprising a bottom plate and upright, and meanscarried by said plate for looking engagement with the platform, asdescribed.

2. In a device for unrolling cloth or other fabrics, the combination,with a base having a central opening and a downwardly-extending collarsurrounding the opening, a platform provided with a central opening anda sleeve surrounding the opening and extending downward from theplatform loosely through the collar of the base, the lower end of whichsleeve is provided with a nut, ballbearings located between the opposingfaces of the platform and the base, a screw-brake carried by the baseand engaging with the under face of the platform, and a socket formed atthe upper portion of the platform, consisting of a collar havingrecesses in its upper edge, of a sustaining member for the bolt or roll,consisting of an upright adapted to be passed through the centralportion of a bolt or roll, a bottom plate upon which the lower portionof the bolt or roll is adapted to rest, a pin extending from the baseand adapted to be loosely passed through the sleeve of the platform, andstuds extending from the plate at opposite sides of the pin, adapted toenter the recesses in the socket on the platform when the pin of thesaid sustaining member is entered in the sleeve of the platform, as setforth.

In testimony whereof I have signed my name to this specification in thepresence of 'two su bsoribing witnesses.

HARRIS L. ROSENTHAL.
